In info node "(emacs) Regexp Search", I've found this paragraph:

     Just as in ordinary incremental search, any <SPC> typed in
  incremental regexp search matches any sequence of one or more whitespace
  characters.  The variable ‘search-whitespace-regexp’ specifies the
  regexp for the lax space matching, and ‘M-s <SPC>’
  (‘isearch-toggle-lax-whitespace’) toggles the feature.  *Note Special
  Isearch::.

I think that this paragraph would need some rewording, because the
variable 'isearch-regexp-lax-whitespace' is nil by default (unlike
'isearch-lax-whitespace', which is t by default).

Thanks, the doc could be improved as follows:
